Answer 1

The definition of 1 KWh is as follows: 1 KWh is the amount of energy consumed by an electric appliance working with a power of 1Kilowatt i.e. 1000Watts, in a time interval of 1 hour. So when an appliance with power of 1000W operates for 1 hour, we say that it has consumed 1 KWh amount of energy.

Answer 2

Explanation:

One thousand Watts is one kilowatt, abbreviated kW. That's a measure of power. If you use one kilowatt of power for an hour, you have used 1 kilowatt-hour, abbreviated kWh, of energy. One kilowatt-hour is equivalent to the energy of 1,000 joules used for 3,600 seconds or 3.6 million Joules.
